Question 1 Report

Which of the following rock types is coal associated with?
Answer Details
Coal is associated with organically-formed sedimentary rocks. Coal forms from the accumulation and transformation of plant material over millions of years under heat and pressure. These organic materials include leaves, wood, bark, and other plant remains that are buried in sedimentary basins. As they are subjected to heat and pressure, they undergo chemical and physical changes that eventually transform them into coal. Therefore, coal is typically found in rocks such as shale, sandstone, and limestone that were formed from sediments deposited in swamps, lakes, and other wetland environments where plant material could accumulate.
